WIP: test(KMP): use mockative instead of mockito

[riQQ]

Preparation for the move to KMP.

~150 tests are still failing. Some are blocked by bugs / missing features in Mockative, but maybe some or all of the failing tests can be changed to work around the issue or to just don't mocks.

Also, I read somewhere that (at least) JavaScript does not support the fun `my quoted function name`() syntax and therefore this syntax cannot be used in multiplatform projects. I am not sure if this also applies if one does not target JS at all. But if it does, I guess all the nicely readable test functions would need to be renamed from fun `my cool function name`() to fun my_lame_function_name() (or worse, camelCase, but ...🤮)

(There are conflicts with master and the PR is marked as draft, that's why I didn't look at it in detail yet. In case you need feedback about something, let me know.)

I've seen this error at some point, I think when writing a test for a Mockative bug. So you're correct that we'll have to rename the methods when switching to the KMP project structure.

Yes, that's why this PR is still a draft. I don't want to put in the work if Mockative doesn't fix / implement everything that is required for the tests here. Progress has slowed down there so I'm waiting, too.

Mockative is looking for a new maintainer, so this PR depends on Mockative getting a new maintainer.

See mockative/mockative#129.

Mockative and that other one not being compatible with K2, it sounds to me that Mokkery would be the only remaining option (for us), if it has the features we need.

What a coincidence! I just joined the OpenStreetMap site last week as I'm looking for non-corporate alternatives to Google maps! I just saw the bad news about Mockkative 😔 - I hope I can support this nifty effort!
